COMPOSITION FOR COATING CARBOYS OR OTHER VESSELS.

SPECIFICATION forming part of Letters Patent N 0. 668,275, datedFebruary 19, 1901.

Application filed April 9,1900. Serial No. 12,248. (No specimens.)

T0 aZZ whom, it may concern:

Be it known that I, FRANCOIS AROHAM- BAULT, chemist, a citizen ofFrance, residing at 94 Coors Lafayette, Lyons, France, have inventedcertain new and useful Improvements in Composition for Coating Carboysor other Vessels, of which the following is a specification.

The object of the present invention is a coating unattackable by acidsor by humidity, lighter and cheaper than the actual packing, and of asmall volume, which can be applied on any kind of carboy, bottles, andother objects of glass or pottery ware or on'casks or other like vesselsfor the nrpose of protecting them from breakag from shock or from damagefrom fire or acids.

This coating or paste is composed of one hundred parts, by weight, ofpul verize ork one hundred parts of silicate Q r i an fifteen parts ofamiant ms in powder. 'I iese three substances, mixed together withoutaddition of water, form a plastic mass which is spread on the carboys orother objects to be protected. This first layer, more or less thick,according to the volume of the object, forms a thoroughly water-tightenvelop which in case of inner fissures prevents the liquid fromescaping even if it is a very powerful acid. This first layer is alsounattackable by the humidity of cellars, whereas ordinary packing orcoverings decay through damp.

This paste dries relatively in a very short time-about ten minutes-andmakes a complete substance with the object on which it has been applied.

To place this paste easily on objects to be covered when they arevoluminous, and especiallycarboys, I take a mold of wood or othermaterial, in halves, havinga section of about two centimeters largerthan that of the carboy. I place on these two parts of the mold twopieces of some fabric which is not closely woven, such as lightpacking-canvas, gauze, &c. I place the carboy in the mold, pressingtogether the two parts, and then introduce the paste between the canvasand the carboy, pressing it well into all parts with a spatula or otherinstrument. The carboy is taken out and dried.

By giving the articles coated as described another tl 1i r 1 c oatingwith another composition of fifty part"s ','by weightfam antlius andtwenty-four parts silic the objects provided with the two coatings areunattackable by fire, in consequence of the amianthus which covers themexteriorly.

The stoppers or bungs should be surrounded by amianthus-silicate paste,so as to produce a hermetic closing.

I declare that what I claim is 1. A composition for coating carboys andother vessels consisting of powdered cork, amianthus, and silicate ofpotash, the weight of silicate of potash being in excess of theamianthus.

2. A composition for coating carboys and other vessels consisting ofpowdered cork, powdered amianthus and silicate of potash, the cork andsilicate of potash being equal in Weight and in excess of the amianthus.

3. A composition for coating carboys and other vessels consisting of onehundred parts of powdered cork, fifteen parts of amianthus and onehundred parts of silicate of potash.

4. A carboy having a coating composed of powdered cork, amianthus, andsilicate of potash, the weight of silicate of potash being in excess ofthe amianthns.

5. A carboy having a coating composed of powdered cork, powderedamianthus and silicate of potash, the cork and silicate of potash beingequal in weight and in excess of the amianthus:

6. A carboy having a coating composed of one hundred parts of powderedcork fifteen parts of amianthus and one hundred parts of silicate ofpotash.

7. A carboy having a coating composed of powdered cork, amianthus, andsilicate of potash, the weight of silicate of potash, being in excess ofthe amianthus, with an exterior coating composed of amianthus andsilicate of potash.

8.
